yourself, but instead you will implicitly or explicitly use the global

is designed so that the ``working_set`` is used by default, such that you
don't have to explicitly refer to it most of the time.

called by the ``WorkingSet()`` constructor during initialization.
This method uses ``find_distributions(entry,False)`` to find distributions
This method uses ``find_distributions(entry, True)`` to find distributions
corresponding to the path entry, and then ``add()`` them. `entry` is
always appended to the ``entries`` attribute, even if it is already
present, however. (This is because ``sys.path`` can contain the same value
for obtaining an "importer" object. It first checks for an importer for
the path item in ``sys.path_importer_cache``, and if not found it calls
each of the ``sys.path_hooks`` and caches the result if a good importer is
found. If no importer is found, this routine returns an ``ImpWrapper``
instance that wraps the builtin import machinery as a PEP 302-compliant
"importer" object. This ``ImpWrapper`` is *not* cached; instead a new
instance is returned each time.

``pkgutil.get_importer()``, and instead of ``pkg_resources.ImpWrapper``
instances, it may return ``pkgutil.ImpImporter`` instances.)

Release Notes/Change History
----------------------------
0.6c10
* Prevent lots of spurious "already imported from another path" warnings (e.g.
when pkg_resources is imported late).
0.6c9
* Fix ``resource_listdir('')`` always returning an empty list for zipped eggs.
0.6c7
* Fix package precedence problem where single-version eggs installed in
``site-packages`` would take precedence over ``.egg`` files (or directories)
